An explosion at the AB Specialty Silicones plant in Waukegan, north of Chicago, has left at least two people dead.
Lenzi said that from information they have gleaned in the preliminary investigation, some of the employees realized something was wrong and alerted others to get out of the building just before the explosion.
Search and rescue personnel have located and are recovering the body of a third employee killed in the explosion and fire at an IL silicone plant. Lenzi says the two missing employees are also presumed dead.
Initially, one body was found at the explosion site.
The search for the two people who remain missing has been suspended and will resume at 9 a.m. local time tomorrow, Lenzi said.
Lenzi said early Saturday it was too early to speculate on what might have caused the explosion.
The blast was heard miles away and the force shredded the plant, leaving little more than the skeleton of the building standing. He says the coroner was on scene and crews are classifying the search as a recovery.
The company, AB Specialty Silicones, manufactures and distributes various grades of silicone products, CBS Chicago reports. Two others declined medical treatment. Officials from the Occupational Safety and Health Administration will investigate. "We have had no instances as far as code violations or anything like that with the plant".
Over 100 firefighters responded to the blast from at least 30 different fire departments, Lenzi said.
The Lake County Sheriff's Office tweeted Friday that they were aware of a "very loud explosion" and "ground shaking" felt near the Gurnee-Waukegan border.
Megan Hener, who lives six blocks from the scene told The Lake County New-Sun the explosion was "massive" and the "building was leveled".
"I've had friends from Antioch, Grayslake and Libertyville call to see if I am all right", she said.
Lenzi said authorities have concluded that the explosion and fire was accidental.
The cause of the explosion has not yet been determined.
